About Program and Definition Updates

LiveUpdate obtains program updates and definition updates for your computer by using your Internet connection.

Program updates are minor improvements to your installed product. These differ from product upgrades, which are newer versions of the entire product. Program updates are usually created to extend the operating system or hardware compatibility, adjust a performance issue, or fix program errors. Program updates are released on an as-needed basis.

Some program updates may require that you restart your computer after you install them.

LiveUpdate automates the process of downloading and installing program updates. It locates and obtains files from an Internet site, installs them, and then deletes the older files and downloaded definitions from the temporary folder after processing the updates.

Definition updates are the files that keep your Symantec products up to date with the latest antithreat technology. The definition updates that you receive depend on which product you use.

The type of definition updates that each of the Symantec products receive are as follows:

Norton AntiVirus, Norton AntiVirus Online

Norton Internet Security, Norton Internet Security Online
